Motorola Moto G 2023 Smart Watch
No coating described, and no PFAS statement from the brand.
The product information we reviewed describes stainless steel case, elastomer band, with no water-repellent coating named. Water resistance on products like this usually comes from the material and its seals rather than a surface treatment. The brand has published no PFAS statement for it.

What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Elastomer band degradation and microplastic release
Elastomer bands can develop micro-cracks and surface erosion under UV, sweat, and mechanical stress over 2-3 years of daily wear. While full breakdown into microplastics is not typical for silicone bands at normal use temperatures, degraded surfaces may shed particles. No testing data is available for this specific band formulation.
Stainless steel alloy composition uncertainty
While stainless steel is not a material linked to PFAS concerns, nickel content varies by alloy grade (typically 6-12% in 304 stainless). Individuals with nickel sensitivity or dermatitis may experience localized skin reaction from prolonged contact with the case back. Motorola does not publicly disclose the specific stainless steel grade or nickel percentage.
Seal degradation and moisture intrusion
User reports and warranty data for smartwatches commonly document seal failure after 12-24 months, leading to internal corrosion and battery leakage. While the Moto G 2023 carries an IP rating for waterproofing, seals are not replaced during normal use and degrade predictably.
Battery leakage and chemical exposure
Lithium-ion batteries in wearables occasionally fail or swell, risking internal electrolyte leakage. If the case remains sealed, exposure is contained; if seals fail, caustic electrolyte could contact skin or eyes. No specific battery supplier or chemistry details are disclosed for this model.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Heavy metals
Circuit boards and internal solder joints may contain lead (phased out in EU but still present in some non-EU manufacturing). However, no direct skin contact occurs, and no internal leakage pathway is documented for intact units. Risk is negligible under normal use.

What it's made of and why it matters
The Moto G 2023 smartwatch uses a stainless steel case, which is chemically inert and does not leach metals under normal use or moisture exposure. The elastomer (rubber/silicone) band is a synthetic polymer; quality elastomers are non-porous and resistant to degradation from sweat and water. No ceramic glazes, enamel coatings, or Teflon-type coating-based treatments are described for this model, eliminating the typical hazard pathways found in older smartwatch designs.
The brand's record and disclosure
Motorola (owned by Lenovo) does not publish formal PFAS statements or use-phase safety certifications for wearables in publicly available materials. The absence of a coating description and silence on PFAS suggests either avoidance of fluorinated water-resistance treatments or lack of transparency. No significant recalls or contamination incidents specific to Moto wearables are documented in public records.
How it compares in its category
Stainless steel casebacks are industry standard for fitness trackers and avoid the lead or cadmium risks associated with cheaper plated metals. Most competing models (Apple Watch, Garmin, Fitbit) also use stainless steel or aluminum; elastomer bands are the norm. This product sits in the lower-concern middle of the category, with no distinguishing premium materials or disclosed safety certifications that would elevate it above peers.
If you buy it
Clean the band regularly with soap and water to prevent bacterial colonization in creases, especially after sweating. Avoid prolonged exposure to extreme heat (above 60C/140F) which can degrade elastomer over time. Inspect the band for cracks or color fading annually; replacement elastomer bands are widely available and inexpensive. Do not submerge beyond the stated IP rating; seals degrade over years of use.
